ATTORNEY the grade crossing orf `anImvrrr cA'rTLn-e'Uann f To all whom t may concern:

Be it known that l, Mrorranr. V. TRUHAN, a citizen of theUnited States, residing at Bridger, in the co-untyof Carbon and State of Montana, have invented `certain' new and useful lmprovements in Railway Cattle- Guards, of which the 4following-is a specification. z y f Myeinventicn relatesto cattle guards for railwaysvand has particular reference to a new `andimproved device arranged adjacent other non-fenced portion of 'a railway track forpreventing the trespassing thereupon of animals.

The primary object of my invention is to provideacattle guard of the class described which' -s simple in construction, strong and durable, effective in operation, and cheap to manufacture and install. i

With the above and other objectsin view my invention resides preferably in the construction," combination and arrangement of parts as hereinafter set forth in the speci cation and illustrated in the accompanying drawings, in which,

Figure 1 is a top plan view of a railway cattle guard including the preferred embodiment of my invention.

Fig. 2 is a transverse sectional view on the line 2-2 of Fig. 1.

Fig. 3 is a fragmentary longitudinal sec tional view taken on the line 3-3 of Fig. 1 looking in the direction of the arrow.`

Fig. 1 is an enlarged fragmentary elevational view of one of the elements forming the barrier.

Similar reference characters designate corresponding parts throughout the various views of the drawings.

1n the drawings, wherein the preferred embodiment of my invention is illustrated, 1 have shown a railway track comprising the running rails 10 mounted as usual on the cross ties 11. My invention comprises three sections or structures, which may be identical in size and form, one of said sections being arranged between the running rails, and the other sections being arranged outside of the running rails. 1n view of the fact that these sections may be identical I shall describe but one of the same, however, the three sections are designated in their entirety as A, B and C.

The barrier or guard comprises preferably a pair or more of stringers 12 and 13 arranged in spaced parallel relation on the ties taken Specification of LettersPateilt.

11. The extremities of thestringers 12 `and 13 are arranged in spaced parallel relation on the ties 11. rlhe extremities of the stringers 12 and 13 are bolted or otherwise secured as at 14 to the ties 11, as shown to advantage in Figs. 1 and 3. The stringers 12 and 13 form a frame for supporting the barrier members whichare constructed for oscillation `or rotation in the frame to provide an insecure footing for an animal which will tend to frighten or prevent the animal from` going upon the track either `way from the grade crossing. As `shown to advantage in Figs. 2 and `3 the leading guard or barrier com- 1G having stub shafts 17 extendingefrom the i opposite ends thereof and `mounted in suitable bearing openings formed in the stringers 12 and 13. A plurality of prongs 18 and 19 extend rearwardly and upwardly from said beam 16 and serve the purpose hereinafter setforth. A platform 20 is carriedby one side of the beam 16 and extends forwardly of the barrier in the direction of the grade crossing (not shown) so that when an animal steps upon the same the platform will be tilted, as shown in dotted lines in Fig. 3, presenting an insecure footing for the animal. ln order to return the platform 2O to normal position 1 provide a pair of arms 22 having loops 23 on their free eX-` tremities connected with coil springs 24: fastened to one of the ties 11. 1t will thus be seen that the platform 20 is depressed against the action of the springs 24. In the guarding devices B and C only one of said springs is provided in view of the fact that said guarding device would be in most in stances narrower than the centrally located barrier A. In order to limit the downward movement of the platform 2O and thereby prevent catching the animals hoof, a stop `25 is provided on one of the stringere.

Should the animal succeed in passing the depressible platform 2O a pluralitv of rotatable bars 26 are mounted on the stringers 12 and 13, said bars having stub shafts 27 similar to the stub 16 hereinbefore described. A plurality of radiating prongs 28 are carried by the various faces of the bar 2G and notonly serve to provide an insecure footing for th-e animal, but will impinge upon the animals foot causing the animal to necessarily withdraw. As shown to advantage in Fig. 4 the spikes kor prongs 1S, 19 and 28 are preferably proshafts 17 of the beam` Y plicable.

vided with threaded shanks 29 to permit the renewal of the prongs in case of damage to the same. It will be noted that the prongs shown in Fig. l are of a slightly different shape from those shown in theremaining figures of the drawings, but this does not necessarily enter into the invention, any desired shape-of prong being ap- It will be readily apparent that more than one of the depressible platforms 20 may be vemployed on a single frame in conjunction with Lthe other guarding devices. v s f F rom the above description taken in connectionl with the laccompanying drawings 1t isrthought that a clearand comprehensive understanding -of the construction, operay"tion and advantages vof my invention may and while I have shown and described the same as embodying a specific structure I desire that'it be understood that I may make such changes therein which do not depart from the spirit and scope of the invention as claimed.

- I claim;

- 1. In a cattle guard, the combination with be readily gathered,

Y the frame, of a plurality of rotatable Yspiked 011e ofthe bars at bars on the frame, a d'epressible platform on t-he entrancev to the frame,

Copies of this patent may be obtained for ve cents each, by addressing the bars mounted on the frame, a depressible platform secured to one of the bars at the longitudinal entrance to the frame, stops at either side of the platform bar, and a resilient member for holding the platform in engagement with one of the stops, the other stop beingadapted to limit the downward movement of the depressible platform when depressed by a weight.

3. In arailway cattle guard, the combination with the frame arranged parallel with the rails, of a plurality tatably supported on the frame, a spring pressed platform mounted on one of the bars at the head and entrance end to the frame, and stops arranged at the side of the platform supporting bar for table movement of the platform bar.

In testimony whereof I aiiix my signature in presence of two witnesses.
